<br>
can you check the output of "can … status" before and after death?
Do the rx/tx counters still grow after death?<br>

having problems with IncomingFrameCan when reading from two can
buses from the Kia Soul. One of the can buses dies prematurely,
and quite fast, with no visible errors. Most of the time it is
Can2 that dies, however that is not always the case.
<div class="">I tried with an almost empty IncomingFrameCan2,
containing just a counter to see how many times it is called,
and it varied from 15 to almost 200 before it dies. </div>
